摘　　要：分别用有限差分法的早期方法、井水位优化方法和奇点磨光法计算实例中井水位。由实例计算并比较显示,奇点磨光法计算得到的井水位与井处真实水位最接近。Based on finite difference method, we use early method, well level optimization method and pol-ishing singular point method to calculate the well level in example respectively. The example is calculated and compared. The well level calculated by polishing singular point method is closest to the real well level.
